The physi-cal environment is one of strong tidal ciurents flowing over a hardsand, shell or gravel substrate, and the characteristic faunal assem-blage is best represented at 46°S (around Otago). The communityhas been recognized as far south as 54°42S, where Fusitriton wascommonly less dominant, and farther north where Fusitriton wasabsent.

There is no fossil record of Fusitriton in New Zealand (Flem-ing, 1967, written communication) although Chlamys delicalularanges back to uppermost Pliocene in fossil communities suitablefor Fusitriton.
